Parallelizing code is always hard to do programatically and is harder to get right - given the advances in multi-core technology.

For example, assume you apply predicates on a set of [in-memory] data (e.g. a cache be it...]]> Tue, 02 Oct 2007 13:01:26 -0400 Tue, 02 Oct 2007 13:01:26 -0400 Tue, 02 Oct 2007 13:01:26 -0400 Oct 2, 2007 James Watson 0 Re: Java's been ready for many-core era; how about you? http://www.theserverside.com/discussions/thread.tss?thread_id=47085 Tue, 02 Oct 2007 12:06:23 -0400 Tue, 02 Oct 2007 12:06:23 -0400 Tue, 02 Oct 2007 12:06:23 -0400 Oct 2, 2007 Krishnan Subramanian 3 Re: Java's been ready for many-core era; how about you? http://www.theserverside.com/discussions/thread.tss?thread_id=47085 For example, this is direction Microsoft has taken with its Language Integrated Query (LINQ) in the upcoming version of .NET (C# 3.0).

There are systems that need distributed (or, more likelly, partitioned) caches, but it will take along time before it becomes the "mainstream" solution.
